I have certain questions to ask about quasars: ============================================== 1.)how are they formed.? 2.)what happens to them in the end? 3.)why is that quasar sometimes stop emmiting radio waves? 4.)are there any quasers nearby our solar system. 5.)what is relationship of quasers and BLACK HOLES Please Register or Log in to view the hidden image! bye!
Zion, here are some (partial) answers: 1) nobody knows exactly what quasars are, they are very intense sources of energy (equivalent to 10s of millions of stars), quite concentrated (thus the word 'quasi-stars' that became quasars), and with a very important redshift in their light, thus supposedly extremely far and belonging to "the young universe". Their light look very similar to light from core of galaxies called 'Seyfert' galaxy, that is very very active, powerful radio emission. The most popular theory is that It's giant blackholes at the center of young galaxies. The collapse of matter and other starts into these giant blackholes create these 'whirlpool' of energy. (by the way I also answered to your #5) 2) Well I don't know what you mean by 'in the end'... these giant blackholes - if the theory is correct - probably 'eat' all the matter of their host galaxy then become 'wandering' giant blackholes in the Universe. (possibly an important source for the mysterious 'missing dark matter' in the Universe?) 3) I've not heard about any quasar stopping emmitting...do you have some precise reference? 4) definitely not. They are within the farthest objects observed/detected in the accessible visible universe.... Hope this helps, Ben
1.)how are they formed? Quasars I think, are spinning black holes. 2.)what happens to them in the end? I imagine they evaporate just like any black hole. 3.)why is that quasar sometimes stop emmiting radio waves? I have not heard of this. 4.)are there any quasers nearby our solar system. I don't know. 5.)what is relationship of quasers and BLACK HOLES Quasars are spinning black holes.
Zion, These should come close to answering your questions. Start with this: http://webferret.search.com/click?wf,quasars,,www.phys.vt.edu/~jhs/faq/quasars.html,,aol http://www.geocities.com/CapeCanaveral/Hangar/4317/ http://webferret.search.com/click?wf,quasars,,info.aoc.nrao.edu/pr/quasars.html,,aol If you are curious I turned up 500 items.

THANKS Thanks wet 1 i have got all of my answers. Hi Chagur, initially they didnt work,as i tried ti acces them...now they are all working fine. bye!
please permit a most humble reply on a subject I know so little about it. Is it possible that the whole question of black holes is arbitrary as it is based on some dense object preventing photons excaping from its surface. But if one were to increase the density be 3 orders of magnitude what then. Do you think it possible that Quasers are minute fragments of material decomposing from the big bang and that they are at thier present positon at T minus a small number. A bit like fragments of casing from an exploded had grenade. humble
